Original Abstract Submitted
An injection molding machine includes a cylinder; an injection member housed within the cylinder; and a molten resin supply device connected to the cylinder and configured to pump a molten resin from a position closer to a proximal end of the injection member than to a distal end of the injection member. In the cylinder, a pumping force applied to the molten resin by the molten resin supply device is used to move the molten resin in front of the injection member, and the molten resin is accumulated on a front side of an internal space of the cylinder. The molten resin is injected from the distal end of the cylinder by moving the injection member forward.
